BOTTLE-RACK-ACTUATING DEVICE FOR BOTTLE-POLISHING MACHINES.

Application filed February This invention relates to bottle polishing machines of the type wherein a row of bottles is pressed against the periphery of a rapidly rotating polishing drum.

More particularly the invention relates to a bottle rack actuating device for polishing machines of this class.

One important object of the invention is to provide an improved construction wherein two bottle racks or holders will be alternately moved by novel mechanism, into position for reciprocation tangentially to the surface of a polishing drum.

A second important object of the invention is to provide a novel construction of machine wherein such bottle racks, in moving from loaded or polishing position to the unloading and loading position, will be automatically tilted from vertical to horizontal position, the mechanism serving to restore the racks to vertical position as they are moved back to polishing position.

A third important object of the invention is to so arrange such mechanism that it may combine with a reciprocating mechanism whereby, upon the bottle racks being moved to polishing position, they will be engaged by the reciprocating mechanism and caused to reciprocate tangentially of a revolving polishing drum.

A fourth important object of the invention is to provide a novel arrangement of this class wherein the rack being loaded will be out of engagement with the reciprocating mechanism and will remain quiescent during the loading or unloading of the bottles.

With the above and other objects in view, as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifi' cally claimed.

In the accompanying drawings like char.-

Figure 2 is a plan view of the front portion of such a machine.

Figure 3 is a section on the line 33 of Figure 2 but with the positions of the bottle racks reversed.

Figure 4 is a section on the line 44 of Figure 3.

Figure5 is a detail to enlarged scale and showing that portion which particularly effects tilting of the racks to vertical position.

In the embodiment of the invention herein disclosed there is shown a polishing machine having a frame which is indicated in general at 10. On the upper part of this frame is mounted a shaft 11 whereon is carried the polishing drum 12 which is provided with a suitable pan 13 and hood 14 properly secured to the frame 10. At the rear of the machine is a jack shaft 15 on which is fixed a pulley 16 which is connected by a belt 17 with a similar pulley 18 fixed upon the shaft 11. The shaft 15 is driven from some suitable source of power such as is indicated by the belt 19. Projecting forwardly from the lower front part of the frame 10 is a pair of brackets 20 to which are pivoted the lower ends of the side members of a swinging frame 21 having at its upper end a bracket 22 wherethrough slides a rod 23. The rear end of this rod is held by a bracket 24 projecting up from the rear portion of the frame 10 and on the projecting front end of this rod is mounted a spring 25 one end of which bears against the front of the bracket 22 while its forward end is engaged by an adjusting hand wheel 26 screwed on the rod23 and serving to regulate pressure urging the top of the frame 21 rearwardly.

On this swinging frame are rearwardly extending guides 27 wherein are mounted the reciprocating bars 28, these bars being connected by a cross bar 29 having its forward face bevelled as shown for purposes which will be presently explained. Secured to the under side of this cross bar are forwardly projecting supporting rails 30 and lateral guide bars 31. Extending forward from the reciprocating frame 28 are the bearing brackets 82 wherein is ournalled the shaft 33 having at each end a erank disk 34. i rejeeuag radially from e'aeh of the disks LJI 34 is a crank arm 35 which is connected by a link 36 with the respective end of a bot-tle rack or carrier 37. This bottle rack rests slidably on the rails 30 and is guided at its ends by the guides 31. It will be seen that the rack is of L shape and that abottle placed on the rack rests with its base against the base of the L and its side against the stem or upright portion of said L.

Extending from the frame 28 at the ends of the cross bar 29 is a second pair of guide or supporting rails 38. Each of these rails first extends upwardly and forwardly at an acute angle to the frame 28 and then curves forwardly into a horizontal portion. Slidably mounted on the rails 38 is a second bottle rack 39 of exactly similar character to the rack 37 and, like it, connected to the disks 30 by links 40 and radial crank arms tl. To one of the disks is alsoeonnected an operating lever 42.

On the lower front portion of the frame is supported a shaft 43' on which is a pulley 44 connected by a belt 15 with a pulley 16 on the shaft 15. The shaft 13 is also provided with a pair of crank disks 47 which are connected by links or rods 48 with the reciprocating frame 28.

In order to understand the operation of the device let it be supposed that the racks are as shown in Figure 1 and the shaft 15 -to he revolving. Under these conditions it will be plain that the drum 12 will be revolving and the rack 39 will be moving up and down in front of thedrum so that the bottles carried by this rack will each have one side pressed against the drum and be moved tangentially thereto. Meanwhile the rack 37 may be loaded if empty or unloaded and reloaded if full. It is to be understood that, if it is desired to polish more than one side or part of the bottles, such unloading and reloading may simply take the form of turning the bottles around. In any event, after the bottles on the rack 30 have been sufficiently polished in their present position, the lever 42 is drawn forward. This will cause the rack 39 to tilt backward and glide up the rails 38 until it assumes the position shown in Figure 3. At the sametirne the rack 37, with its fresh load of bottles will move forward from the operator until it engages the bevel face of the cross bar 29. On arriving at this position furthermovement of the lever 12 will cause it to tilt upward as shown in Figure thus bringing its bottles into contact with the polishing drum. It is obvious that a reverse movement of the lever will restore the racks to their original positions.

There has 'thus been provided a simple and etficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invent on without departing from the spirit thereof and accordingly it is not desired to confine the invention to the exact form here shown and described but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new is 1. In a device of the kind described, a polishing drum, a bot-tle rack movable rectilinearly toward and from the drum, means connected to the rack for imparting said movement thereto, and a rack tilting device interposed in the path of said rack, said rack being tiltable between horizontal and vertical positions.

In a device of thekind described, a polishing drum, rack supporting rails extending from points adjacent the drum, a bottle rack slidably mounted on said rails to move toward and from the drum, said rack being tiltable between polishing position adjacent the drum and loading position remote from the drum, means to eliect movement of the rack on said rails, and a rack tilting device fixed in the path of said rack adjacent said drum.

3. In a device of the kind described, a polishing drum, rack supporting rails extending away from said drum from points adjacent thereto, a bottle rack slidably mounted on said rails to move therealong toward and from the drum, said rack being tiltable between polishing position adjacent the drum and leading position away from the drum, a rack tilting bar extending above said rails adjacent the drum, and means to reciprocate the rack on said rails.

4-. In a device of the kind described, a polishing drum, rack supporting rails extending away from said drum from points adjacent thereto, a bottle rack slida-bly mounted on said rails to move therealong toward and from said drum, said rack being t-ilta-ble between polishing position and loading position, a rack tilting bar extending above said rails adjacent the drum, a shaft extending transverse said rails in spaced relation to the drum, crank means carried by the shaft, links connecting said crank means with the rack, and means carried by the shaft for rocking the same.

5. In a device of the kind described, a polishing drum, rack supporting rails extending away from said drum from points adjacent thereto, a bottle rack sl-idably mounted on said rails to move therealong toward and-from said drum, said rack be ing tiltable between polishing position and loading position, a rack tilting bar extending above said rails adjacent the drum, a shaft extending transverse the rails in spaced relation to the drum, crank means carried by the shaft, links connecting said crank means with the rack, means carried by the shaft for rocking the same, other rails extending away from said drum from points adjacent the drum, a second bottle rack slidable on the last mentioned rails and also tiltable between polishing and loading positions, said tilting bar being also in the path of the second rack, other crank means carried by said shaft, and links connecting the last mentioned crank means with the second rack, said crank means being arranged to cause the racks to move in opposite directions.

In testimony whereof I aflix my signature.
